Each device consists of four independent voltage comparators designed specifically to operate from a single power supply and typically to draw 60-µA drain current over a wide range of voltages. Operation from split power supplies also is possible and the ultra-low power-supply drain current is independent of the power-supply voltage. Applications include limit comparators, simple analog-to-digital converters, pulse generators, squarewave generators, time-delay generators, voltage-controlled oscillators, multivibrators, and high-voltage logic gates. The LP239, LP339, LP2901 were designed specifically to interface with the CMOS logic family. The ultra-low power-supply current makes these products desirable in battery-powered applications. The LP239 is characterized for operation from −25°C to 85°C. The LP339 is characterized for operation from 0°C to 70°C. The LP2901 is characterized for operation from −40°C to 85°C.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values, except differential voltages, are with respect to the network ground. 2. Differential voltages are at IN+ with respect to IN −. 3. This input current only exists when the voltage at any of the inputs is driven negative. The current flows through the collector-base junction of the input clamping device. In addition to the clamping device action, there is lateral n-p-n parasitic transistor action. This action is not destructive, and normal output states are reestablished when the input voltage returns to a value more positive than − 0.3 V at TA = 25°C. 4. Short circuits between outputs to VCC can cause excessive heating and eventual destruction. 5. If the output transistors are allowed to saturate, the low-bias dissipation and the on-off characteristics of the outputs keep the dissipation very small (usually less than 100 mW). 6. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ of 150°C can impact reliability. 7. The package thermal impedance is calculated in accordance with JESD 51-7.

This current essentially is constant (i.e., independent of the output state). No loading change exists on the reference or input lines as long as the common-mode input voltage range is not exceeded. 10. The output sink current is a function of the output voltage.

CMOS Driver All pins of any unused comparators should be grounded. The bias network of the LP239, LP339, and LP2901 establishes a drain current that is independent of the magnitude of the power-supply voltage over the range of 2 V to 30 V. It usually is necessary to use a bypass capacitor across the power supply line. The differential input voltage may be larger than VCC without damaging the device. Protection should be provided to prevent the input voltages from going negative by more than −0.3 V. The output section has two distinct modes of operation: a Darlington mode and ground-emitter mode. This unique drive circuit permits the device to sink 30 mA at VO = 2 V in the Darlington mode and 700 µA at VO = 0.4 V in the ground-emitter mode. Figure 3 is a simplified schematic diagram of the output section. The output section is configured in a Darlington connection (ignoring Q3). If the output voltage is held high enough (above 1 V), Q1 is not saturated and the output current is limited only by the product of the hFE of Q1, the hFE of Q2, and I1 and the 60-Ω saturation resistance of Q2. The devices are capable of driving LEDs, relays, etc. in this mode while maintaining an ultra-low power-supply current of 60 µA, typically. VCC I1 = 6 µA Q3 VO Q1 Q2 Figure 3. Output-Section Schematic Diagram 4 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 The LP239 is obsolete and is no longer supplied. SLCS004B − OCTOBER 1987 − REVISED SEPTEMBER 2004 APPLICATION INFORMATION Without transistor Q3, if the output voltage were allowed to drop below 0.8 V, transistor Q1 would saturate, and the output current would drop to zero. The circuit would be unable to pull low current loads down to ground or the negative supply, if used. Transistor Q3 has been included to bypass transistor Q1 under these conditions and apply the current I1 directly to the base of Q2. The output sink current now is approximately I1 times the hFE of Q2 (700 µA at VO = 0.4 V). The output of the devices exhibits a bimodal characteristic, with a smooth transition between modes. In both cases, the output is an uncommitted collector. Several outputs can be tied together to provide a dot logic function. An output pullup resistor can be connected to any available power-supply voltage within the permitted power-supply range, and there is no restriction on this voltage, based on the magnitude of the voltage that is supplied to VCC of the package.
